In 2026, energy strategy has become as important as product quality when planning a new automated biscuit production line. Global tunnel oven demand continues to grow, driven by higher levels of automation, energy-efficiency requirements, and expanding biscuit consumption in emerging markets. At the same time, biscuit producers face volatile electricity and gas prices, as well as pressure to cut emissions and improve overall equipment effectiveness (OEE). [insights.made-in-china]
From Wenva Machine's perspective as a dedicated automated biscuit production line manufacturer, the oven decision is no longer simply "electric or gas", but "which configuration delivers the lowest total cost per baked kilogram over 10–15 years of operation". In this article, we will compare electric vs. gas tunnel ovens across operating cost, energy efficiency, product quality, sustainability, and integration into modern biscuit lines, using real industry data and practical field insights. [hg-machine]
A tunnel oven is the thermal backbone of a high-output biscuit line, linking dough forming to cooling and packaging. In a typical Wenva line, dough mixing, forming, baking, cooling, and packaging are designed as a continuous, synchronized system to maximize throughput and minimize waste. [gelgoog.en.made-in-china]
Modern tunnel ovens for biscuits usually feature multiple heating zones, independent temperature and airflow control, and precise conveyor speed regulation. These capabilities allow manufacturers to bake different biscuit types on the same line with tight control of color, moisture, and texture. [wenvamachine]

| Aspect | Electric Tunnel Ovens | Gas Tunnel Ovens |
|---|---|---|
| Primary energy | Electricity from grid or renewables aocno | Natural gas or LPG combustion aocno |
| Heat delivery | Electric heating elements, radiant and convective aocno | Direct or indirect-fired burners, high radiant heat aocno |
| Temperature precision | Very tight control, often within ±1 °C aocno | Good control, typically slightly wider band aocno |
| Typical use cases | Plants with strong decarbonization goals or high electricity reliability aocno | Large-scale, 24/7 production where gas is cheaper than power aocno |
| Installation complexity | No flue gas handling, simpler exhaust aocno | Requires combustion systems, burners, chimneys, gas trains aocno |
Industry suppliers report that advanced electric ovens now offer temperature variation as low as ±1 °C across the baking chamber, supporting extremely consistent biscuit color and moisture. Gas ovens, while slightly less precise, deliver very strong heat load and fast recovery, which benefits very high-speed tunnel lines. [aocno]
From a cost perspective, energy price per unit of heat remains the dominant factor when comparing electric and gas tunnel ovens. In many countries, gas still offers a lower cost per kilowatt-hour of thermal energy than electricity, but this gap is narrowing where renewable power and industrial electricity contracts are incentivized. [cognitivemarketresearch]
When Wenva engineers help clients evaluate oven type, we usually start with three questions that align with broader industry practice: [knoxnews]
1. What is the ratio of electricity price (per kWh) to natural gas price (per cubic meter or kWh-equivalent) in your region?
2. Are there tax credits, subsidies, or carbon pricing schemes that favor all-electric or low-emission equipment?
3. What is the planned utilization: single shift, two shifts, or 24/7 continuous production?
Market analyses indicate that industrial tunnel oven buyers now focus on energy consumption benchmarks, often targeting below 0.8 kWh of energy per kilogram of baked product for competitive lines. Highly optimized gas tunnel ovens can meet or beat this benchmark, especially on large, continuous runs. Electric ovens can reach similar or better specific energy consumption when combined with efficient insulation, heat recovery, and smart controls, particularly where electricity comes from low-cost or on-site renewable sources. [insights.made-in-china]
While exact cost depends on local tariffs, a common pattern in 2026 is: [linkedin]
- In regions with cheap pipeline gas and standard grid electricity, gas tunnel ovens usually deliver lower energy cost per kilogram of biscuits.
- In markets with high gas prices, strong renewable generation, or green tariffs, electric ovens can be cost-competitive or even cheaper over the equipment lifetime.
Modern tunnel ovens for biscuits use advanced insulation, zoned heating, and optimized airflow to reduce energy losses and improve baking uniformity. Some lines also integrate infrared or hybrid technologies to shorten bake time and reduce overall energy consumption. [hg-machine]
Electric ovens typically convert electrical energy to heat with very high efficiency at the point of use, and they avoid stack losses associated with flue gas. Gas ovens can reach high combustion efficiency through modern proportional burners, with some suppliers reporting energy utilization above 95% in optimized systems. [aocno]
For sandwich biscuits, cream-filled products, and products where color differences must be minimized, tight temperature and humidity control becomes a critical differentiator. Electric ovens excel here due to fine-grained power modulation and fast response of heating elements. [insights.made-in-china]
However, some bakers still prefer gas-fired ovens for specific breads or cookies where combustion moisture and radiant heat contribute to a desirable crust or bite. For high-output biscuit lines, Wenva typically balances these preferences with the customer's target SKUs and quality specifications during line design. [wenvamachine]
Sustainability has become a strategic driver for oven selection as governments and retailers tighten carbon requirements. Electric tunnel ovens offer a clear pathway to decarbonization, especially when plants can source renewable electricity or deploy solar and storage systems. [cognitivemarketresearch]
In regions with strong carbon pricing or mandatory emissions reporting, shifting to all-electric process heat can simplify compliance and improve ESG scores, which increasingly influence long-term customer contracts. At the same time, engineers and environmental experts are collaborating to introduce greener energy solutions across biscuit lines, reducing reliance on fossil fuels while keeping costs under control. [linkedin]
Gas ovens still play a major role, particularly where infrastructure favors gas and where full electrification of process heat would require major grid upgrades. For such plants, the realistic compromise may be highly efficient gas tunnel ovens combined with heat recovery, better insulation, and digital monitoring to cut waste. [hg-machine]
Fully automatic biscuit production lines combine dough preparation, forming, baking, cooling, and packing into a synchronized flow. Oven type directly impacts plant utilities planning, including electrical substation sizing for electric ovens and gas supply/piping design for gas ovens. [gelgoog.en.made-in-china]
Modern biscuit lines increasingly adopt IoT-based sensors and real-time monitoring to track oven zone temperatures, belt speeds, and product characteristics. These systems allow operators to optimize recipes, reduce energy usage, and minimize rejects by fine-tuning baking curves in response to data. [insights.made-in-china]
Industry cases show that integrating smart sensors for temperature and humidity along the line can significantly reduce waste and downtime. Electric ovens pair naturally with advanced PLCs and digital control algorithms, while gas ovens rely on coordinated burner management systems and safety interlocks to maintain stable conditions. [wenvamachine]
For Wenva Machine, the most successful projects are those where oven control logic, upstream forming, and downstream cooling/packing are designed together, enabling recipe-based changeovers and precise control of baking profiles for different biscuit types. [gelgoog.en.made-in-china]
Market reports project steady growth in the global tunnel oven sector through the mid‑2020s, driven by rising demand for packaged baked goods and continued investment in industrial baking infrastructure. At the same time, buyers are putting increased emphasis on energy consumption metrics, changeover efficiency, and compatibility with automation and digitalization strategies. [knoxnews]
In the biscuit segment, automated lines have evolved rapidly, incorporating higher levels of control, better sustainability features, and greater flexibility to support SKU proliferation and health-oriented products. Leading exporters are investing in lines that can meet international retailer requirements on food safety, traceability, and environmental performance, making oven technology a strategic choice rather than a purely technical one.
